Anatomical structure of the Syrinx in the mallard (Anas platyrhynchos)

Bu çalışmada erişkin dişi ve erkek yeşilbaş ördeklerde (Anas platyrhynchos) syrinxin normal anatomik ve histolojik özelliklerinin incelenmesi amaçlanmıştır. Ağırlıkları 1244±114 g olan sekiz adet yeşilbaş ördek (beş dişi, üç erkek) incelendi. Syrinxin tracheobronchial tip olduğu ve tympanum, cartilagines tracheosyringealis ve cartilagines bronchosyringealisten meydana geldiği gözlendi. Tympanum ve cartilagines tracheosyringeales sırasıyla dört ve altı kıkırdak halkasından, cartilagines bronchosyringeales ise C şeklinde kıkırdak halkalarından oluşmuştu. Pessulusun kısmen kemiksel bir yapıda olduğu ve cavum syrinxin içine doğru kama şeklinde uzadığı saptandı. Syrinxin erkek ördeklerde asimetrik olduğu ve sol tarafta bulla tympaniformis adı verilen büyük bir genişleme yaptığı tespit edildi. Sağ ve sol bronchus primariusların gergin bir ligamentum interbronchiale ile birbirine bağlandığı görüldü. Membrana tympaniformis medialisin pessulus ile 3.. cartilago bronchosyringealis halkası arasında uzandığı saptandı. Membrana tympaniformis lateralisin son tympanum halkası ile 1. cartilago bronchosyringealis halkası arasında bulunduğu tespit edildi. Histolojik incelemede hem pessulusun hem de syrinksin kısmen kemiksel yapıda olduğu belirlendi.

Yeşilbaş ördekte Syrinx in anatomik yapısı (Anas platyrhynchos)

The aim of this study was to investigate the normal anatomical and histological features of the syrinx in adult male and female mallards (Anas platyrhynchos). Eight mallards (five female, three male) weighing 1244±114 g were examined. It was observed that the syrinx in mallard was tracheabronchial type formed by tympanum, cartilagines tracheosyringeales and cartilagines bronchosyringeales. Tympanum and cartilagines tracheosyringeales were formed from four and six cartilage rings, respectively, while cartilagines bronchosyringeales was formed from C-shaped cartilage rings. It was found that pessulus was contained ossified tissue partially and was extended into cavum syrinx as wedge-shaped. It was determined that syrinx in male ducks was found to be asymmetrical and had a large expansion on the left side called bulla tympaniformis. The right and left bronchus primarius were bound together by a tight ligamentum interbronchiale. Membrana tympaniformis medialis was extending from pessulus to the 3th cartilago. bronchosyringealis ring. Membrana tympaniformis lateralis was found to be between the last tympanum ring and the 1st cart. bronchosyringealis ring. Histological examinations of both pesulus as well as syrinx partially ossified structure were determined.
